Parasitic on the trunks of trees. Roots fibrous, brown. Leaves distichous, 
recurvo-falcate, acute, laterally compressed, and thus vertical, fleshy, 
glaucous green, grooved at the base for the reception of the lower part 
of those leaves which are placed immediately above them. 
Scape axillary from the base of the plant, four or five inches high, panicu- 
late, branched almost from the base, the branches as well as the branch- 
lets alternate, distichous and patent, slender, terete. Bracteas small, 
green, placed at the base of every flower, and of every ramification, su- 
bulate. Flowers collected into conical heads at the extremity of the ra- 
muli, small, pale yellow-green, resupinate, according to the common ac- 
ceptation of the term, as applied to this family ; that is, the germen is 
not twisted, and the parts of the inflorescence are in their proper situa- 
tion. Petals nearly equal; upper ones, or segments of the perianth the 
smallest, oblong, united together for more than half their length from 
the base. Two lateral petals very concave, so as to be almost semicy- 
lindrical, but when spread open they are nearly ovate. Lower petal 
ovate, very gibbous at the back. Lipa little longer than the corolla, 
standing forward, and somewhat appressed to the column, oblong, 
grooved, 3-lobed, green at the base, deep orange at the extremity, late- 
ral lobes small, middle one large, recurved, all acute. Column oblong, 
laterally compressed, grooved in front, and near its upper part bearing 
the concave stigma. Anther large, transversely oblong, whitish, opercu- 
liform, fixed by the back, 1-celled, glandular on the 
Pollen-masses 2, linear-oblong, deep yellow, fixed near the extremity of | 
a linear white stalk ; and this, at its base, has an oblong, orange coloured | 
gland, which stands out beyond the top of the column, and just beneath | 
the closed anther.
